These nightgowns are made to give you a comfortable sleep night after night. Our special blend of 95% Cotton and 5% Spandex is not like other fabrics out there. Our research and development on this fabric is second to none. These nightgowns are modest, with a crew neck that is meant to cover the neckline, the 3/4 sleeves to cover the elbows, and the length, to cover the knees even while sitting (for women of average height)
